The correct option is B) “A snowstorm threatens their lives and forces them to seek shelter.” The reason why Slateh and Aaron spend days in the haystack is because a snowstorm took Aaron by surprise when he was taking the goat to the town. Even though Aaron did not agree with taking the goat to the butcher, he was obeying his father's orders.
Option C) is incorrect as it was not getting dark, it was the snowstorm that stopped him.
Option D) is also incorrect since Zlateh suspected that something wrong was happening but did not offer any resistance to move further.
